VT machining specialises in CNC EDM Drilling SKD11 Tool Steel. Because SKD11 Tool Steel is wear-resistant and hardenable for tooling, and its machinability is machined in the annealed state, then hardened; carbide tooling preferred, we plan each job around the grade to protect accuracy and surface quality.
CNC EDM Drilling Capability for SKD11 Tool Steel
- Air/oil/water-hardening grades
- High wear resistance
- Hardenable to 58–64 HRC
- Tolerance to ±0.005 mm

Published typical values for WC-Co (YG8 / K20). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Everything is done by grinding, wire EDM or sinker EDM. Design in a small corner radius wherever possible — a true sharp internal corner doubles the EDM time.
Machining SKD11 Tool Steel with CNC EDM Drilling
The machinability of SKD11 Tool Steel is machined in the annealed state, then hardened; carbide tooling preferred. For CNC EDM Drilling we select tooling, feeds, speeds and coolant to match, keeping the SKD11 Tool Steel workpiece stable and the result accurate.
Because we machine SKD11 Tool Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC EDM Drilling SKD11 Tool Steel
| Feature | Standard | Precision |
|---|---|---|
| Profile dimension | ±0.010 mm | ±0.002 mm |
| Internal corner radius | 0.15 mm | 0.05 mm |
| Taper control over 50 mm | 0.02 mm | 0.005 mm |
| Surface finish (skim passes) | Ra 0.8 µm | Ra 0.2 µm |
| Recast layer | 10 µm | 2 µm (fine skim) |
| Start-hole diameter | 1.0 mm | 0.25 mm |
| Workpiece hardness | no limit (conductive) | no limit (conductive) |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Design Tips for CNC EDM Drilling SKD11 Tool Steel
A few design choices make a real difference to cost and quality. EDM suits sharp internal corners, thin ribs and hardened SKD11 Tool Steel that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
Why SKD11 Tool Steel?
Specifying SKD11 Tool Steel for CNC EDM Drilling SKD11 Tool Steel is usually about its properties: wear-resistant and hardenable for tooling. Tell us the condition you need and we machine to it.
CNC EDM Drilling Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on SKD11 Tool Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the SKD11 Tool Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Secondary Operations & Finishing
We complete SKD11 Tool Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Applications of CNC EDM Drilling SKD11 Tool Steel
CNC EDM Drilling of SKD11 Tool Steel supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

What We Need to Quote CNC EDM Drilling SKD11 Tool Steel
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact SKD11 Tool Steel grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
